Yes indeed, it works better this way. But then, I have 2 http servers running on the same box. Thank you to all those who have replied, Laurent michel@digicool.com said:
<guess> You must still use medusa (ZServer, in this case) even if you want to use PCGI (which is what Zap uses). ZServer listens to many protocols, like HTTP, FTP, and PCGI. If you don't use medusa, PCGI will try to fire up Zope the OLD way, and it will probably work but it's not the right way. The problem is, now your process environment has the wrong LD_LIBRARY_PATH (and a whole slew of other problems related to running Zope the old way, like no concurrency) and cannot find your Oracle dynamic libraries.
Run ZServer first. Then Zap. Then it should work.
